Two boats in a fleet race (Hobie 17s) are finishing downwind. No other boats nearby. RC is to the left, pin is to the right. Boat A is on port tack and is just inside the lay line to finish by the pin. No danger of not making the finish line on current tack. Boat B is on starboard and has overlap when Boat A enters the zone, but Boat B does not have the line made (pointing outside the pin). As the two boats come together, Boat B gybes with more speed than Boat A and ends up right beside and windward of Boat A. There's a chance that Boat B could sneak ahead of Boat A at the finish. Boat A is leeward and pushes Boat B up (to the left) and hails "leeward, come up". Boat B hails, "you've got plenty of room". Question is, if both boats are finishing in the three boat zone but Boat A didn't need Boat B to maneuver to give room rights to get past the pin, can Boat A take Boat B up (left) to keep her off the line and then bear off (right) to shoot the line. Or are room rights in play at the pin and Boat A is required to sail proper course and cannot use leeward rights to push Boat B off the line?
